Abstract
A fabric coating composition, comprising from 2 to 50 dry parts of a crosslinking polymer, from 5 to 60 dry parts of a polymeric binder; from 2 to 30 dry parts of pigment fixation agents, parts are based on total dry content of the coating composition; a pH control agent in an amount adjusted to have a pH above 7; and an aqueous liquid vehicle is described. The coating composition is used to be applied to a fabric print medium. Also described herein are a coated fabric printable medium, a method for forming the coated fabric printable medium and a method of textile printing that includes ejecting an ink composition onto the coated fabric print medium described herein.
Claims15
1) A fabric coating composition, comprising:
- a. from 2 to 50 dry parts of a crosslinking polymer,
- b. from 5 to 60 dry parts of a polymeric binder;
- c. from 2 to 30 dry parts of a pigment fixation agent, parts are based on the total dry content of the coating composition;
- d. a pH control agent in an amount adjusted to have a pH above 7;
- e. and an aqueous liquid vehicle.
12) A coated fabric print medium, comprising:
- a. a fabric base substrate;
- and
- b. a coating layer applied on, at least, one side of the fabric base substrate, the coating layer including from 2 to 50 dry parts of a crosslinking polymer, from 5 to 60 dry parts of a polymeric binder;
- from 2 to 30 dry parts of pigment fixation agents, parts are based on total dry content of the coating composition;
- a pH control agent in an amount adjusted to have a pH above 7;
